Question

最近，当我打算在我的PC上使用Windows 8.1完成我的工作时，我发现项目无法正常工作 - 它编译，在模拟器上运行并在某些特定点崩溃（它是在我的电脑上100％可重复）。

但是，相同的存储库修订版适用于工作中的Mac和我的同事Windows 10计算机。

每个提到的环境都使用Android Studio 2.3.1，gradle 3.3和Kotlin 1.1.1，并在API 25 x86_64图像上运行应用程序。

该项目正在使用multidex 1.0.1库。

由于以下异常而发生崩溃：

BaseActivity.kt

abstract class BaseActivity : RxAppCompatActivity(), HasErrorHandler (...)

SomeActivity.kt - 此次崩溃

class SomeActivity : BaseActivity(), HasFullWindowProgress (...) {

    (...)

    private fun getDataFor(id: String) {

        apiClient.somethingList(id)
                .map { response -> response.toSomethingList() }
                .lifecycle(this)
                .showProgress(this)
                .observeOnMainThread() // <== line 164
                .subscribe({
                    LOG.info("Something list fetched ${it.size}")
                    adapter.setItems(it)

                }, defaultOnError("Fetching something list failed"))
    }
}

AnotherActivity.kt - 使用与SomeActivity相同的功能，不会崩溃

class AnotherActivity : BaseActivity(), HasFullWindowProgress (...) {

    (...)

    private fun getData() {
        somethingElse.user?.id?.let { id ->

            apiClient.somethingElseList()
                    .map { response -> response.toAnotherList(id) }
                    .lifecycle(this)
                    .showProgress(this)
                    .observeOnMainThread()
                    .subscribe({
                        onNewSomethingElseList(id, it)
                    }, defaultOnError("Fetching somethingElseList for somethingElse failed"))
        }

    }
}

ActivityErrorHandlingExtensions.kt

fun <T> T.defaultOnError(message: String, vararg args: Any?): (Throwable) -> Unit where T : HasErrorHandler, T : Activity {
    val targetClass = javaClass
    val activity = this
    return { err ->
        val messageFormats = (args.toList() + err).toTypedArray()
        LoggerFactory.getLogger(targetClass).error(message, *messageFormats)
        errorHandler.default(err, activity)
    }
}

ObservableExtensions.kt

fun <T> Observable<T>.lifecycle(activity: RxAppCompatActivity) : Observable<T> {
    return compose(activity.bindToLifecycle<T>())
}

fun <T> Observable<T>.observeOnMainThread() : Observable<T> {
    return observeOn(AndroidSchedulers.mainThread())
}

Progress.kt

fun <T> Observable<T>.showProgress(hasProgress: HasFullWindowProgress): Observable<T> {
    return compose {
        it.doOnSubscribe {
            MAIN_THREAD_WORKER.schedule {
                hasProgress.fullWindowProgress.visibility = View.VISIBLE
            }
        }.doAfterTerminate {
            MAIN_THREAD_WORKER.schedule {
                hasProgress.fullWindowProgress.visibility = View.GONE
            }
        }
    }
}

所有这些代码都在项目中持续了一两个月，两周前它在我的电脑上运行。

我已经尝试过：

./gradlew cleanBuildCache
已删除$HOME/.gradle/caches
已删除$HOME/.android/build-cache
已删除$HOME/.AndroidStudio2.3/system/caches
已删除build和app/build dirs
在项目根目录中删除了.gradle dir
Android Studio使缓存无效并重新启动
手动从模拟器中卸载应用程序并再次安装
重新安装Android Studio 2.3.1
将Android Studio降级为2.3（这是我2周前使用的版本，我知道它的工作原理）

这里有什么想法吗？

Answer 1

几周前我遇到了类似的问题。这基本上是我为避免ClassNotFoundException所做的，在我的情况下是由于Multidex＆＃34;配置＆＃34;更新Android Studio，gradle等后

将compile 'com.android.support:multidex:1.0.1'添加到app gradle文件中的依赖项列表中。

从Application类的Multidex.install(this);方法中删除onCreate()，并在Application类中添加以下内容：

@Override
protected void attachBaseContext(Context context) {
    super.attachBaseContext(context);
    MultiDex.install(this);
}

我在更新了gradle版本等后遇到了错误，所以请确保你的所有内容都是最新的。

希望它有所帮助。

Android项目中的ClassNotFoundException仅在我的PC上
